Display screen or portion thereof with an animated graphical interface



FIG. 1 is a front view of a first implementation of a display screen or portion thereof with an animated graphical interface showing a first image in the sequence showing my new design;

FIG. 2 is a second image thereof;

FIG. 3 is a front view of a second implementation of a display screen or portion thereof with an animated graphical interface for a tablet computing device showing a first image in the sequence showing my new design;

FIG. 4 is a second image thereof;

FIG. 5 is a front view of a third implementation of a display screen or portion thereof with an animated graphical interface for a computer display or monitor showing a first image in the sequence showing my new design;

FIG. 6 is a second image thereof;

FIG. 7 is a front view of a fourth implementation of a display screen or portion thereof with an animated graphical interface for a smartwatch showing a first image in the sequence showing my new design; and,

FIG. 8 is a second image thereof.

The dashed lines, broken text, and broken graphics illustrate portions of the display screen or portion thereof with an animated graphical interface that form no part of the claimed design. The appearance of the animated images sequentially transitions between the images shown for each of the four implementations, FIGS. 1-2, 3-4, 5-6, and 7-8, respectively. The process or period in which one image transitions to another forms no part of the claimed design. 

CLAIM I claim the ornamental design for a display screen or portion thereof with an animated graphical interface, as shown and described.
